A standard deck of cards has 52 cards, 13 of each of the 4 suits: hearts, diamonds, clubs, and spades. after shuffling the deck, linbo deals the cards to his friends for the game. which expression can be used to find the probability that the first three cards that he deals are all hearts if none of them are replaced? (startfraction 13 over 52 endfraction) (startfraction 12 over 52 endfraction) (startfraction 11 over 52 endfraction) (startfraction 13 over 52 endfraction) (startfraction 12 over 51 endfraction) (startfraction 11 over 50 endfraction) (startfraction 13 over 52 endfraction) (startfraction 13 over 52 endfraction) (startfraction 13 over 52 endfraction) (startfraction 13 over 52 endfraction) (startfraction 13 over 51 endfraction) (startfraction 13 over 50 endfraction)
The probability that the first three cards that he deals are all hearts if none of them are replaced will be [tex]\rm P = \frac{13}{52} \times \frac{12}{51} \times\frac{11}{50}[/tex].
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.
Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
The given data in the problem is ;
Total number of the card in the deck = 52
No of hearts = 13
If one heart is taken out one at a time we will get the probability that the first three cards that he deals are all hearts if none of them are replaced
From the total card one by one the cards is taken out without the replacement;
Without replacement, the card will be reduced by 1Also the heart card will also be decreased by one.
The probability that the first three cards that he deals are all hear will be;
[tex]\rm P = \frac{13}{52} \times \frac{12}{51} \times\frac{11}{50}[/tex]
Hence option B is correct.

A rectangular prism has a length of 4m, a height of 11m, and a width of 17m. What is its volume, in cubic m?
Answer:
748m³
Step-by-step explanation:
Hello!
The volume of a rectangular prism is determined by the formula [tex]l * w * h[/tex]. To find the volume is to find how much space the object takes up in 3D. The formula is used to find the area of the base ( [tex]l * w\\[/tex] ), or the space taken on a 2D plane and multiplied by the height to give it 3 Dimensions.
Breakdown of [tex]l * w * h[/tex]:
[tex]l[/tex] is length[tex]w[/tex] is width[tex]h[/tex] is heightFind the Volume:
Use the formula and plug in values into the formula.
V = l * w * hV = 4 * 17 * 11748Th units of length are m, and volume is the units cubed, so the units are m³.
The volume is 748m³
Answer:
748
Step-by-step explanation: V= W*H*L
17*11*4= 748m^3

y = 157y/38 - 3,321.485
Answer:
The answer is, y = 1060.64
Step-by-step explanation:
First, you want to multiply both sides by 38, which gives you
38y = 157y -126216.
Then you want to rearrange:
119y = 126216
then you want to divide by 119, which gives you y=126216/119, which is 1060.64

what is the first step to 11-3x=44 ?
Answer:
Subtract 11 both sides to isolate the variable and it's cooeficient.
Step-by-step explanation:
Given equation:
11 - 3x = 44The main goal to determine the solution of the equation is to isolate the variable that is present in the equation.
(1) Subtract 11 both sides to isolate the variable and it's cooeficient.
(2) Simplify if possible.
(3) Divide the cooeficient (-3) both sides to remove the cooeficient from the variable.
Once the variable has been isolated, the opposite side of the variable will be the solution to the variable.
⇒ 11 - 3x = 44Step-1: Subtract 11 both sides
⇒ 11 - 3x - 11 = 44 - 11⇒ -3x = 44 - 11Step-2: Simplify (if possible)
⇒ -3x = 44 - 11⇒ -3x = 33Step-3: Divide the cooeficient of x (-3) both sides
⇒ -3x = 33⇒ -3x/-3 = 33/-3⇒ x = -11Therefore, the first step in simplifying the expression (11 - 3x = 44) is to subtract 11 both sides to isolate the variable and it's cooeficient. When the expression is simplified, we get the solution x = -11.
The diameter of a circle is 5 in. Find its area to the nearest hundredth.
Answer:
19.63 in²
Step-by-step explanation:
Given:
[tex]\text{Diameter of circle: 5 inches}[/tex]
Determine the radius of the circle:
The relationship between the diameter and the radius of the circle is that the diameter is two times larger than the radius. Thus, the diameter needs to be divided by two to obtain the radius of the circle.
⇒ Diameter/2 = Radius⇒ 5 inches/2 = Radius⇒ 2.5 inches = RadiusDetermining the area of the circle:
The area of the circle is πr². Let's substitute the measure of the radius to determine the area of the circle.
⇒ πr² = Area of circle⇒ π(2.5)² = Area of circleSimplify the square of 2.5:
⇒ π(2.5)(2.5) = Area of circle⇒ 6.25π = Area of circleReplace π with 3.14 (Approx.):
⇒ 6.25(3.14) = Area of circle⇒ 19.625 in² = Area of circleFurthermore, the question said to round to nearest hundredth...
⇒ 19.63 in² = Area of circle

What is the standard deviation of the shoe size data for the math class? 1.5 2.7 3.0 3.8
The standard deviation is the maximum and the minimum variation in the data set from the mean. The value of the standard deviation is 1.5.
What is a standard deviation?The standard deviation is the maximum and the minimum variation in the data set from the mean.
Given that the mean shoe size is 7.5, while the size of shoe for the entire class is only 1 deviation, and the value is 6 and 9. Therefore, the equation of the standard deviation and the mean can be written as,
[tex]\mu -\sigma < x < \mu +\sigma \\6 < x < 9[/tex]
Now, the value of the standard deviation can be written as,
[tex]\mu - \sigma = 6\\\\-\sigma = 6-7.5\\\\-\sigma = -1.5\\\\\sigma = 1.5[/tex]
or the value of the standard deviation can be written as,
[tex]\mu + \sigma = 9\\\\ \sigma = 9-7.5\\\\ \sigma = 1.5[/tex]
Hence, the value of the standard deviation is 1.5.

What is Histogram?A histogram is a graph that depicts the frequency distribution of a few data points from a single variable. Histograms frequently divide data into "bins" or "range groups" and count the number of data points that belong to each of those bins.
The bar graph graphically represents category data. A histogram is a graph that represents quantitative data. Each pair of consecutive bars is separated by an equal amount of space.
The data from the Histogram can written as
